Stair Riser Too High. A stair stringer is a structural member that supports the treads and risers of a staircase. As we explained above, the most common stair riser defects likely to lead to a fall include:

Most of the time, when your stair is going from one platform to another, the riser height is determined by the overall height difference. Osha 1910.25 (c) (2) requires standard stairs to h ave a maximum riser height of 9.5 inches (24 cm). The height of the stair should be reduced by 1 to 2 inches.
For Spiral Stairs, The Rise Should Be No More Than 9 ½ Inches.
Correction and further evaluation is recommended. The maximum height of a riser on a stair structure is 2.5 times the minimum height. Or, put another way, the maximum height of a riser can be no more than 35 millimeters (1.4 inches) high.
This Code Specification Was Developed To Prevent Stairs From Being Too High If Walking Upstairs Or Too Low If Descending.
Clamp and nail a 1/4 plywood template to the outside of the stringers (skirts removed), 1/4 below the current tread, run a 2 flush trim router bit over the tread, removing the 1/4 necessary to correct to the consistent riser height. The greatest riser height within any flight of stairs should not exceed the smallest by more than 3/8 inch. But what defines what is too high and what is too low will.
A Stair Stringer Is A Structural Member That Supports The Treads And Risers Of A Staircase.
Overhangs on stair treads are not required if the treads are 11 inches or less. This still leaves the bottom step 1/4 high because it is currently 1/2 high. Typically, there are three in a staircase:
You Can Increase The Desired Number Of Risers But Not Decrease.
When the step is too high you'll have to lift your foot higher, making it inconvenient. Both stairs that are too high and too low can result in a staircase that is uncomfortable to climb. One on each side, and.

To answer your question about the risers being different from the treads.i think it is a good traditional look to paint the risers and skirt boards of a staircase while leaving the treads stained.
